I need some lights for my roadie that I can use during the daylight to improve my chances of being seen by cars etc.
Ideally, I would like something that is very compact and doesn't use up batteries too quickly. Basically, something I can stick on and forget, until the batteries need replacing.
Any recommendations?

Skully's, small light and bright, I got mine from on-one, don't know if they still do them but worth a look
The sun and road positioning.
Unless it's pishing down then I don't see why people now feel the need to have bike lights on during the day.
Anyway have you looked at the exposure lights?
Exposure Flash with the rechargeable battery option is pretty small but very bright as a front light.
Dyno hub with decent lights (eg Busch & Muller)
As a high mileage driver and a lifelong cyclist - my view is that lights on a bike are close to useless from a motorist's perspective in the day and ESPECIALLY small ones.
It's not about how bright they are they're still small and small lights at close range are easily obscured by car blind spots, street furniture and the like.
If you go for lights for daytime use the larger the surface area and brighter the better (within reason) one of those 5 or 7 LED wide ones on the back would be good. Much harder to lose that behind the A-Pillar of a car than a single dot.
If you want to be seen then wear something bright and ideally reflective.
What makes a cyclist (or anything else on the roads) visible in good to moderate daylight is contrast between them and the surrounding environment (whether that's pure colour or reflections of light from flat surfaces).
Around town I reckon wearing a high-vis vest is the way to go if you can live with the fashion faux-pas (I almost always do and I carry one when out on a ride in case I get caught out at dusk and need to pound some tarmac).
Having said all that I have a neat little 5 LED light from Topeak as my (night time/evening) backup that I take on the MTB and darkside bikes.
To be honest, I am not sold on the idea myself, but I'm tempted to try them out, although testing whether they work or not is not really something that is easy to do. As a driver myself, I do see the benefit of motorbikes having their lights on during the day, albeit ones that are somewhat brighter and larger than your average bike light.
Now hi-viz vests: I am even less convinced by those, especially after driving up behind a cyclist the other day and not even seeing he had a hi-viz on until I was right on top of him (metaphorically speaking, of course). I saw his lights no problem.
I'm not convinced by high viz either and not just as a fashion faux pas. There's so many high viz cyclists out there that I reckon drivers become oblivious to them. From an article I read recently high viz makes no difference.

"Like all good waterproof Day-Glo cycling jackets, this will allow you to simmer in your own sweat on your commute to work and enable you to look like a complete pr1ck when you have to wear it around town in your lunch hour.
But what really makes this jacket stand out are its powers of invisibility. Slip it on, get on your bike and you completely disappear. It has to be seen to be believed."
